You can also use multiple bearings to find where you are on a map.If you aren't on a linear feature like a trail, you can still find where you are on a map. Called "triangulation," this process simply requires you to follow these same steps with a second and a third landmark, pre...
Read the number of degrees on the half-circle protractor directly behind the nylon cord. Given this angle, the known distance from the house, and the angle between house and ground, simple geometry makes it straightforward to calculate the height of the house. Alternately, use a tangent table....
A horizontal angle can be measured usinga magnetic compasswith an outer graduation ring which measures degrees from 0 to 360 in a circle. Because the needle of a magnetic compass always points directly north, you can use it as a baseline for your measurements. Orient your outer graduation ring...
etc. The other thing I do is use an older version of iPolar (2.21, I believe) , as I found the newer version tends to jump around more than the older versions. It doesn't turn red/green, but you can visually see when the circle/ball is aligned with the cross adequately. If y...

is south, and the left is west. The direction from one point to another point (either on the map or on the ground) is called azimuth. Azimuths are given in degrees in a clockwise direction. Since there are 360 degrees in a circle, your azimuth can be any number up to 360. Due eas...
After scratching the line, turn the cell and scratch the circle back and forth again. Maybe turn it once more and scratch it once more. Now flip the cell over and notice the rough stuff on the back. If there appears to be two different roughnesses or shades of grey, we are going to...
However, the findings are difficult to reconcile with the standard models of navigation. Reinforcing the separate use of room and arena spatial features was sufficient to degrade externally referenced directional tuning, in contrast to unreinforced substratal and proximal cues that are reported to lack...

Find the mark of the azimuth N or S. Solution: Plot Altair's position on its dotted line (repr: diurnal circle) according to given hour angle. Take the zenith on the outer circle (repr.: observer's celestial meridian) according to given latitude and draw a straight line (repr.: prime...
